NOTE: If you previously used MultiBeast, start fresh by deleting any HDAEnabler.kext from /System/Library/Extensions, and your current /Extra folder. Then run the appropriate selections from MultiBeast again.

Optionally, you may run DSDT-Free. Here are DSDT-Free MultiBeast settings for both the Z77N and H77N.

Mini-PCIe Card alternatives:
The H77N and Z77N include a mini-PCIe card slot with an Intel mini-PCIe card capable of both Wi-Fi and Bluetooth. Please note that only the bluetooth features of this card are available under OS X. There are alternate cards you can stick in your mini-ITX board for full native Airport. Check out these links for details:

Hi All,
Thanks for putting together this guide. Could have really used it last night doing my first build

Here are a few things I learned:
1) Follow this thread for bios setting: http://www.tonymacx86.com/99-quick-guide-configuring-uefi-gigabyte-s-7-series-lga-1155-boards.html
2) I had to boot unibeast with -x -v on my H77N MB.
3) Do not change the vram size if using HD4000 (default is 64MB)...
4) I installed on a 2TB disk so after installation I had to do this to get it booting without errors. http://www.tonymacx86.com/25-boot0-error-official-guide.html
5) My HD4000 was not recognized after installation to fix it I had to boot using -x -v and then follow this guild with an EFI string for desktop (0162):
<key>device-properties</key>
<string>7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000005006201140000006800640061002d0067006600780000000d0000006f6e626f6172642d31</string>

6) Took a while but all is now working. Thank you EVERYONE that is contributing code, tools and assistance. The community is amazing!

I have the z77n-wifi board with the i3-3225, I have tried to use the dsdt for hdmi audio but it keeps giving me a kernel panic. When I boot with -v it just loops with "invalid character found in processorOP". I have fixed all error and warnings but still have the same problem. The system seems to run fine without the dsdt...Any ideas? Thanks.

I'm thinking of changing my board due to the fact that it's quite difficult to get sleep and speedtest working on my Asus board. I'm going to use my computer as a server running plex so i really need the sleep and speedtest to work.

I had problems with getting my wired ethernet to work after i installed the Atheros wireless card in the GA-Z77N-wifi. The answer was to change my system definition from Mac mini to iMac 12.2

Also, if you are building a dual boot with Mountain Lion and Windows 7, it is critical that the first partition be Windows 7 or it will not install correctly and will stall with your Windows install. My process is to use the USB Mountain Lion/Unibeast install to get the system to boot, partition the drives and then install Windows first, boot from the USB stick again and then install OSX. This way the Chimera boot loader will over right the Windows boot record and it will work right. Another sub-option is to first partition your hard drive externally on another machine and then do the installs.
